The ethylene cracking furnace is divided into a convection section and a radiation section. Generally speaking, the function of the convection section is to recover the waste heat of the flue gas, which is used to preheat and vaporize the raw oil, and superheat the raw oil and dilution steam to the cross temperature of the material, and the remaining Heat is used to superheat ultra-high pressure steam and preheat boiler feed water. In the process of preheating and vaporizing raw materials, dilution steam is injected to reduce the vaporization temperature of raw oil and prevent raw oil from coking during the vaporization process. Each group of disks in the convection section of the cracking furnace The tube is mainly composed of heat exchange furnace tubes (smooth tubes or finned tubes) welded by return elbows. The end tube sheets and the middle tube sheets support the furnace tubes, and the inlet and outlet of some coils are collected together through the header. A group of coils are a ssembled around the furnace wall to form a module
